+   and the backend should take the member list with a getgrgid
+   and ignore any user that have been possibly set into the group
+   object.
+
+   In the second case, the group is a fully SAM managed group
+   served back to the system through winbind. In this case the
+   members of a Local group are "unrolled" to cope with the fact
+   that unix cannot contain groups inside groups.
+   The backend MUST never call any getgr* / getpw* function or
